There is no problem on IP layer.
We test it also with SIP and it is the same. (max retries exceeded on
SIP)
Asterisk drop all calls in few minutes and then working again.
It is happening 3 times per day. In peak there is 90 calls.

I feel that this is a network issue.

If you would like to do some additional testing, you can run something
like wireshark on both ends, and you'll see the packets leave the Asterisk
box, but you won't see them reach the other side (or, if they are, they
aren't returning back properly).

If you can provide pcap traces of both sides where this is not happening,
we would be happy to look into it further.
